Yes, and sometimes even preferred

Littlelesr,

The two procedures are often combined.  The benefit to combining the surgeries are:  one anesthesia session, one recovery period and cost savings.  The prolongation of the operative time may slightly increase the risk rate, but risk precautions keep this possibility very remote.  Occasionally, the tummy tuck tissue that is discarded can be used for the buttock.  In which case, it is obviously preferable to combine the surgeries.  See your board certified plastic surgeon for a discussion of the risks, recovery and expectations of your surgery.  Good luck!
